Valves available in normally closed and normally open constructions. Available in either AC or DC operated with brass SUS304 SUS316 bodies/ stainless steel/ tube/plunger / soft magnetic alloy core.
DIRECT ACTING( from 1/4" to 3/8") and semi - direct acting(1/2" to 2") solenoid valves and do not require a minimum operating differential pressure. As shown below when the coil is energized (right diagram), it lifts the solenoid plunger, which normally rests on the valve seat and lifts it to open the main valve orifice. When the coil is de-energized (right diagram), the spring force the plunger return to the valve seat to close the valve orifice.
